li iClaim.

The invention relates to a snow plow and more especially to the single or double blow type snow plow.

The primary object of the invention is the provision of a plow of this character, wherein the snow is scooped from a road bed or other surface and through the action of a blower or blowers is delivered away from and to one side of such road bed or surface thereby cleaning the road bed or surface or clearing it of snow.

Another object of the invention is the provision of a plow of this character, wherein the scoop has an adjustable shovel end and also a hood, the latter preventing snow from working over the top of the scoop and causing the directing thereof to a blower or blowers for the discharge or delivery of the snow when removed from a road bed to one side of the latter.

A further object of the invention is the provision of a plow of this character, wherein a motor is supported for the driving of the blower 0r blowers constituting an equipment of such plow while within the scoop are bladed wheels which function to direct the snow from the said scoop into the blowers for the deposit of such snow to one side of the path from which the snow is gathered by the scoop.

A still further object of the invention is the provision of a plow of this character, which is simple in construction, thoroughly reliable and efflcient in operation, motivated, readily and easily handled, and inexpensive to manufacture.

With these and other objects in view, the inven ion consists in the features of construction, con bination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred embodiment. of the invention and pointed out in the claim hereunto appended.

In the accompanying drawings:

Figure 1 is a top plan view partly in section of a plov. constructed inaccordance with the invention.

Figure 2 is a vertical longitudinal sectional view thereof showing the shovel end in full lines in working position and by dotted lines in a raised position.

Figure 3 is a vertical transverse sectional view through the blower of the plow.

Figure 4'is a view similar to Figure 1 showing a modified form of plow involving double blowers.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, particularly Figures 1 to 3 inclusive, which is the preferred embodiment of the invention, there is shown a carriage A involving a frame in which is adapted at its rear end for attachment to a truck or the like (not shown). 6

Made secure to the front end of the frame it and inclined forwardly in divergent relation to each other are scoop carrying arms H, these having front skit ends l2 and upon these arms is arranged a forwardly inclined scoop l3 which at the rear end thereof opens into a blower casing M which is supported on and rises from the frame to while interiorly of this casing I4 is a bladed blower fan l5 rotated by a center axle I6 driven from the power shaft I! of an internal combustion motor or engine I8 of any approved type, the latter being fixed or stationary held upon the frame I!) rearwardly of the casing M.

The scoop i3 has at the front open end thereof a plate-like shovel l9 which by the hinges 20 con- 20 nected thereto and to the scoop at opposite sides of the same can be raised and lowered and when in lowered position forms a continuation of the front open end of the said scoop. The bottom of the shovel l9 carries the skid ends l2 which 25 are adapted for separable interfitting with the arms II when the shovel is in lowered working position.

Interposed between the axle l6 and the power shaft I! of the motor or engine I8 is the usual transmission mechanism as held within a transmission box or casing 2|, the throw lever for the control of such transmission mechanism being indicated at 22 and in this fashion the speed and direction of rotation of the axle I6 is regulated.

Bridging the scoop [3 at the inner end thereof and built with the sides of the same is an overhanging hood 23 to prevent snow gathered by the scoop l3 from flowing over the blower casing l4 and at the same time directing such snow into the blower for discharge thereby at one side of the path from which the snow will be gathered by the scoop in the working of the plow. Fitted at a convenient location on the frame I0 is a stationary toothed rack segment 24 with which is associated an adjusting lever 25, it having a hand release spring active latch 26 engageable with the segment 24 so that the lever 25 can be locked or latched in adjusted position. The lever 25 operates a turning shaft 21 suitably journaled crosswise of the frame Ill and through connections 28 therewith operates the shovel IQ for the raising and lowering of the same.

The frame I .is supported upon wheeled casters 23 which travel uponla road bed.

The casing I 4 has the upstanding peripheral.

outlet 30 to which is detachably and adjustably connected 9. laterally directed discharge spout or delivery elbow 3i so that the snow collected by the scoop l3 when directed by the blower will be delivered or discharged through the spout or elbow 3| beyond and at one side of a road bed from which the snow is collected. 1

Within the scoop next to the inner end thereof are bladed beater shafts 32, the .blades thereof tened to the sides of the scoop. i3 to be disposed transversely within said scoop. The outer ends of the shafts 32 are equipped with universal joint fittings 31, these having mounting in the sides of the scoop l3 and one of said fittings has gear and endless chain connections 33 and 33, respectively, with a driven shaft which through-the worm pinion 4i and worm gear 42 is operated from the axle IQ of the fan ii, the shaft 40 being suitably journaled in bracketed bearings 43 stationarily carried by the casing l4. Thus the shaft 32 will be driven from the motor or engine l3 and-when operating will act upon the snow collected by the scoop I 3 for the feeding of the same into the casing l4 to be blown by the fan l5 therefrom through the spout or elbow 3i and disposed to one side of the path from which the snow has been collected by the scoop.

In Figure 4 of the drawings there is shown a modified form of snow plow, wherein there is provided a pair of blower casings 44 each hav- 40 ing within the bladed blower fans 45 and these "aoeacsr through openings 41. The fans are reversely driven through gear and shaft connections 43 and 43, respectively, and the power shaft of the motor or engine if.

Arranged at. the inner end of the scoop next to the casings 44 is a centrally located spreader or divider 52 which functions to divert the quantity ofsnow collected within the scoop 46' into two paths for the feeding of the snow in these paths into the casings 44 and thus burdening the blowers with approximately equal loads to effect the discharge of the snow from the scoop 43 to opposite sides of a road bed where the snow has been collected by the scoop.

What is claimed is:

A snow plow comprising a carriage involving a frame adapted at its rear end for attachment to a truck, forwardly inclined and divergent scoop carrying arms made secure to the front end of the frame and having front skid ends, a scoop superimposed upon said arms, a blower casing on said frame next to the rear end of the scoop and having an eccentric opening communicative with the latter, a motor driven blower fan within said blower casing, a discharge elbow swingingly fitted with the blower casing at its periphery for discharge therefrom laterally with respect to the scoop, across bar fixed transversely in the scoop close to its rear end and abovethe opening between said blower casing and said scoop, a forked bearing fixed centrally to the bar, a pair of bladed beater shafts arranged in forwardly convergent relation to each other and fitting the said forked bearing, a universal joint connecting said shafts within the forked bearing,

universal joints supporting the said shafts jourave
